Brake Pressure Modulator Valve (BPMV) Replacement

REMOVAL PROCEDURE

CAUTION: For safety reasons, the Brake Pressure Modulator Valve (BPMV) must not be repaired, the complete unit must be replaced. With the exception of the EBCM/EBTCM, no screws may be loosened. If screws are loosened, it will not be possible to get the brake circuits leak-tight and personal injury may result.





1. Turn the ignition switch to the OFF position.
2. Disengage the red locking tab from the connector (1).
3. Push down lock tab (1) and then move sliding connector cover (2) to the open position.
4. Disconnect the EBCM/EBTCM harness connector.

IMPORTANT: Note the locations of the brake pipes in order to aid in installation.





5. Disconnect the wheel cylinder brake pipes (1) from the BPMV (2).
6. Swing the four wheel cylinder brakes pipes out of the way only after covering the open pipes to avoid dripping or being contaminated.





7. Disconnect the master cylinder brake pipes (2) from the BPMV (4).
8. It is not necessary to remove the brake pipes (2) from the master cylinder (1).
9. Swing the two master cylinder brake pipes out of the way only after covering the open pipes to avoid dripping or being contaminated.





10. Remove the four bolts (3) that connect the BPMV (1) to the mounting bracket (2).

NOTICE: When removing the brake pressure modulator valve, protect the vehicle exterior from possible brake fluid spillage. Brake fluid can cause damage to painted surfaces.

11. Remove the BPMV and EBCM/EBTCM as an assembly (1) from the vehicle.
12. Remove EBCM/EBTCM if replacing the BPMV only.


INSTALLATION PROCEDURE





1. Install EBCM/EBTCM onto the BPMV (1) if replacing the BPMV only.
2. Install BPMV and EBCM/EBTCM as an assembly (1) to the mounting bracket (2).
3. Install the four bolts (3) that connects the BPMV assembly (1) to the mounting bracket (2).

^ Tighten the four bolts (3) that connect the BPMV (1) to the mounting bracket (2) to 10 Nm (7 ft. lbs.).

IMPORTANT: If a new BPMV is being installed, remove the shipping plugs from the valve openings during the next few steps when ready.

CAUTION: Make sure brake pipes are correctly connected to brake pressure modulator valve. If brake pipes are switched by mistake, wheel lockup will occur and personal injury may result. The only two ways this condition can be detected are by using a Scan Tool or by doing an Antilock stop.





4. Install the master cylinder brake pipes (2) into the BPMV (4).

^ Tighten the master cylinder brake pipe fittings to 24 Nm (18 ft. lbs.).





5. Install the wheel cylinder brake pipes (1) on the BPMV (2).

^ Tighten all four wheel cylinder brake pipe fittings to 24 Nm (18 ft. lbs.).





6. Connect the EBCM/EBTCM harness connector.
7. Push down lock tab (1) and then move sliding connector cover (2) back in home position to lock.
8. Insert red locking tab back in place.
9. When all procedures have been completed, the automated ABS bleed procedure is required.
